Where to Start When Renovating a House: A Step-by-Step Guide for San Diego Homeowners

You know your home needs work. Maybe it’s a kitchen that hasn’t been touched since the 90s, a primary bathroom with builder-grade finishes you’ve never loved, or a floor plan that worked fine for two people but doesn’t work at all for five. You have a sense of what you want — but you’re not sure where to start.

That uncertainty is one of the most common things we hear from homeowners in San Diego who are new to remodeling. This guide walks you through the process in the right order, so you start with what actually matters — and avoid the expensive mistakes that happen when people skip steps.

Step 1: Get Clear on Why You’re Renovating

Before you pick finishes, call contractors, or look at a single inspiration photo, spend real time on this question: what is the actual problem you’re trying to solve?

This sounds obvious, but most people skip it. They arrive with a solution already in mind (“I want to add a bedroom”) without fully articulating the problem (“we have three kids sharing two rooms and there’s no space for anyone to have privacy”). When you understand the problem precisely, you have more options — and sometimes a less expensive option than the one you started with.

Ask yourself:

• What specific things about our home frustrate us every day?
• What are we not able to do in this home that we wish we could?
• Are these functional problems, aesthetic problems, or both?
• Which problems matter most — and which could we live with if budget required?

Write the answers down. They’ll guide every decision that follows.

Step 2: Decide Whether to Renovate or Move

If your home has significant limitations — the lot is too small, the neighborhood doesn’t fit your life stage, or the floor plan is fundamentally incompatible with your needs — renovating may not be the right answer. This is a real question worth sitting with before you invest in a major project.

In San Diego’s current real estate market, the calculus often favors renovating. Inventory is tight, prices remain high, and the transaction costs of selling and buying can easily reach $100,000 to $200,000 on a mid-range San Diego home. If you love your neighborhood and your home’s bones are good, renovation is frequently the smarter financial move.

Step 3: Establish a Realistic Budget

Budget is where most renovation plans run into trouble — not because people don’t want to spend money, but because the mental model for what a home renovation project costs is almost always too low.

Here’s a realistic framework for San Diego remodeling costs:

• Kitchen remodel (full): $80,000–$200,000+ depending on size and finish level
• Bathroom remodel (primary suite):  $40,000–$120,000+
• Whole home remodel: $300,000–$800,000+ depending on scope
• Room addition: $150,000–$400,000+ depending on size and type

These numbers include design, permits, and construction. A useful rule: whatever number you have in your head as your budget, add 15 to 20 percent as contingency. Renovation projects uncover conditions — behind walls, under floors, in electrical panels — that couldn’t be known before construction started.

Step 4: Prioritize What Gets Done First

Fix structural and systems issues first

If your home has a compromised roof, outdated electrical panel, failing plumbing, or foundation issues, those get addressed before cosmetic work. Building beautiful finishes on top of a structural problem is expensive twice — once to build it and once to tear it out and fix the underlying issue.

Address rooms that affect daily life most

Kitchens and primary bathrooms consistently rank as the most impactful renovations for day-to-day quality of life — and they’re the spaces buyers value most at resale. If you use a dysfunctional kitchen three times a day, the impact of improving it is much higher than renovating a guest room you use three times a year.

Think about sequencing

In a multi-phase renovation, sequence matters. Don’t put new hardwood floors down before a bathroom above is replumbed. Don’t repaint before your HVAC contractor runs new ductwork. A good contractor helps you sequence work so you’re not undoing what you just paid to finish.

Plan flooring and household disruption together

Before replacing a wood floor, have its condition assessed to see whether refinishing or targeted repairs could meet your goals. Coordinate flooring with plumbing, electrical work and other construction so new finishes are not damaged or removed for later work. If the house will be empty before move-in, discuss whether that is a practical window for dusty work.

Also decide how the household will function during each phase: protect belongings, plan access to cooking and bathing facilities, and agree whether temporary accommodation is needed. Include those owner expenses and arrangements in your planning.

Step 5: Understand the Permit Requirements

In San Diego, virtually any structural work, electrical upgrade, plumbing change, or addition requires a building permit from the City of San Diego Development Services Department. Unpermitted work creates title problems when you sell, can result in fines, and in some cases requires demolition and rebuilding.

Permit timelines in San Diego range from same-day approval for minor projects to several months for complex additions. Your contractor should manage the permit process on your behalf and factor permit timelines into the project schedule.

Work with a licensed contractor. In California, homeowners are liable for injuries sustained by unlicensed workers on their property. Verify any contractor at cslb.ca.gov.

Step 6: Choose the Right Contractor

The contractor you choose determines the outcome of your renovation as much as any other decision.

What to look for:

• Valid California CSLB license — verify at cslb.ca.gov
• Established local presence and references from San Diego homeowners
• Clear project management process and communication standards
• In-house design capability — design-build firms eliminate the handoff between designer and builder 
• Formal commitment to schedule — not just a verbal promise. That is why we at Lars are proud of our on-time completion guarantee.

Ask for references from recent projects similar in scope to yours. Call them. Ask whether the project finished on time, whether the budget held, and whether they’d hire this contractor again.

Step 7: Go Through the Design Process Properly

Skipping or rushing design to get to construction faster is one of the most expensive mistakes homeowners make. Changes made on paper cost nothing. Changes made after framing is up cost thousands. Changes made after tile is set can cost tens of thousands.

A thorough design process includes space planning, layout development, material and finish selections, detailed drawings for permit submittal, and selections finalized before construction begins.
